Method and device for detecting a current

Abstract

A method and device for detecting a current are described. The present invention displays a value and looks for loads current of the CPU through an LED, a 7-segment display or a display monitor.

1 . A method for detecting a current comprising: 
 transmitting a current detect signal generated by a CPU;    detecting said current detect signal and creating a current value of said current detect signal by a detection unit;    converting said current value of said current detect signal to a voltage value in a conversion unit;    comparing the voltage value with a predetermined voltage value in a comparison operation unit to determine whether the voltage value exceeds said a predetermined voltage value;    determining a voltage dissimilitude value between said voltage value and said predetermined voltage value; and    outputting the voltage dissimilitude value on a display unit.    
   
   
       2 . (canceled)  
   
   
       3 . The method in  claim 1 , wherein the comparison operation unit is a 4-Bit magnitude comparator.  
   
   
       4 . The method in  claim 1 , wherein an output signal of said comparison operation unit is coupled to said display unit only if said voltage value exceeds said predetermined voltage value.  
   
   
       5 . The method in  claim 1 , wherein the display unit is at least one LED.  
   
   
       6 - 12 . (canceled)  
   
   
       13 . A device for detecting a current, comprising: 
 a CPU to generate a current signal;    a detection unit coupled to said CPU to detect the current signal generated by the CPU;    a conversion unit coupled to said detection unit to convert the current signal to a voltage value;    a comparison operation unit coupled to said conversion unit for comparison of said voltage value with a predetermined voltage value; and    a display unit coupled to the comparison operation unit for displaying a voltage dissimilitude value after comparison, the voltage dissimilitude value being determined as a difference between said voltage value and said predetermined voltage value.    
   
   
       14 . The device in  claim 13 , wherein the comparison operation unit is a 4-BIT magnitude comparator.  
   
   
       15 . The device in  claim 13 , wherein the display unit is at least one LED.  
   
   
       16 - 20 . (canceled)
